      @@tarunshalini1180 understood thanks! It's because ISA temperature between 11 to 20kms is -56.5°C whereas the actual temperature @ 14kms is -62°C. Hence ISA deviation is -62 - (-56.5) = -5.5°C. Which means Actual temperature is 5.5°C colder than ISA.

      @MohammedSohxib 5 месяцев назад

      ⁠we know temp temp decreases as we go up and increases as we go down at the rate of 2*C/1000Feet
      Now do the maths. Answer would be fl300 for 11*C
      For question 2
      Temp remains constant between 11km-20km = -56.5 C
      So -62-(-56.5) = -5.5

    • @Cooecolour1
      @Cooecolour1 Год назад +1

      ​@yashbansalvlogsIf you directly apply formula to find the answer you will get 4000ft ie actual. Need to apply the correction of 2° ie 1000ft to the answer...
      For that solve the first part of the question...you will get ISA deviation as 2°C
      Now while solving 2nd part...subtract 2°C to the given temperature ie 11°-2°C = 9°C (Actual-ISA)
      So the equation will be 9°= 15- (alt/1000×2)....6×500=alt ie 3000ft

    [ At a certain position the temperature on the 300 hpa chart is -54^C, and according to the significant weather chart the tropopause is at FL330. What is the most likely temperature at FL350? ] how to calculate altitude by pressure ?

    • @blueskiesandtailwinds6004
      @blueskiesandtailwinds6004  3 года назад +1

      Hi, sorry for the late revert. So if you want to find altitude according to pressure, you can use the ISA pressure lapse rate. Take the pressure at whatever altitude is given in the question and then apply the lapse rate of pressure given in ISA. the same can be used with temperature to find altitude according to temperature, by using the temperature lapse rate. Go through the questions I have discussed in this video and you should be good!

    For your questions, FL should be 20 right instead of 30. As every 1000ft, it decreases by 2 degrees. So from 15 degrees at MSL, it should be 11 degrees, which means we subtract 4 degrees for 2000ft. In the video as well, at 10.08, you calculated temp at 2000 ft to be 11 degrees. Am I missing something here?

      Hi, sorry for the late reply.
      So, use the ISA temperature lapse rate. You know the temperature at a certain altitude (given in the question) and you know the lapse rate (how much drop/gain in temperature is experienced by gaining/losing altitude.
      Keep in mind that when you go up, the temperature falls in the troposphere and when you come down, the temperature increases.
      Just use these basics and you'll be able to get the answer!
